In all primates, the dorsal striatum is divided by a white matter tract called the internal capsule into two sectors called the caudate nucleus and the putamen. The ventral striatum is composed of the nucleus accumbens and olfactory tubercle in primates.
These are: arginine, cysteine, glycine, glutamine, proline, serine, tyrosine. There are 22 Amino Acids. These above are the 20 more well-known amino acids; however, just how many amino acids exist actually are counted as being over 200 in numbers, but the 22 proteinogenic amino acids are the ones that are commonly known.
Chemistry 202 Amino Acids, Peptides, and Proteins Page 1 Amino acids are so called because they have both amino and acid groups in the same molecule. The biologically important ones are a-amino acids; i.e., both functional groups are bonded to the same carbon. The general structure is:
